Rolling Resistance - Engineering ToolBox

The force that resists the motion of a body rolling on a surface is called the rolling resistance or the rolling friction.. The rolling resistance can be expressed by the generic equation. F r = c W (1). where . F r = rolling resistance or rolling friction (N, lb f). c = rolling resistance coefficient - dimensionless (coefficient of rolling friction - CRF)
